Property

A characteristic of a material, such as color, shape, or odor.

Observing Matter

Using your senses to gather information about an object or material.

Describing Matter

Telling about the specific properties of a material.

Measuring Properties

Comparing a property to a standard unit or value.

Meterstick

A scientific tool used to measure the length of an object.

Balance / Scale

Scientific tools used to measure the weight of an object.

Volume Measurement Tools

Liters and milliliters are used to measure the amount of space taken up.

Heat Conductor

A property of a material that allows it to transfer heat easily.

Electrical Conductor

A property of a material that transfers electricity, such as copper wire.

Magnetism

The property of a material that determines if it is attracted to magnets.

Solubility

How well a material dissolves in another material, like water.

Element

A substance that is made up of only one kind of atom.

Atom

The smallest part of an element that still has its properties.

Atomic Theory

The scientific idea that all matter is made of tiny particles.

Compound

Matter made up of two or more different elements combined.

Molecule

The smallest particle of a compound that retains its properties.

Water Molecule

A molecule consisting of one oxygen atom and two hydrogen atoms.

Hydrogen Peroxide Molecule

A molecule consisting of two oxygen atoms and two hydrogen atoms.

Drawing Conclusions

Using data and facts to make a valid logical statement.

Three States of Matter

The primary states of matter are solid, liquid, and gas.

Cause of State Changes

The state of a material depends on the motion of its particles.

Temperature

A measure of how fast the particles in an object are moving.

Temperature Units

Degrees Celsius (℃) and degrees Fahrenheit (℉).

Mass

The amount of matter contained within a substance.

Mass Units

Mass is usually measured in grams (g) or kilograms (kg).

Volume

The amount of three-dimensional space an object or substance takes up.

Volume of Gas

Gas volume changes to fill all available space in its container.

Texture

The surface structure of a material that you can feel by touch.

Hardness

A solid's ability to maintain its shape when pushed or struck.
